Answer to Question 1

The traditional SDLC breaks the system development process into five separate phases or stages.

This leads to a detailed analysis of the existing system and a determination of what the future system should be able to do in the second, analysis phase. The output from this phase has to be converted into a set of detailed design specifications in the design phase.
